Abstract

This invention relates to improved adhesion compositions and textile materials and articles treated therewith. The improved adhesion composition comprises a non-crosslinked resorcinol-formaldehyde and/or resorcinol-furfural condensate (or a phenol-formaldehyde condensate that is soluble in water), a rubber latex, and an aldehyde component such as 2-furfuraldehyde. The composition may be applied to textile substrates and used for improving the adhesion between the treated textile substrates and rubber materials. End-use articles that contain the treated textile-rubber composite include, without limitation, automobile tires, belts, and hoses as well as printing blankets.

First claim

I claim:

1. A method for synthesizing an improved adhesion composition comprising the steps of:
(a) forming an aqueous mixture comprising (i) a water soluble, phenolic condensate material selected from the group consisting of a non-crosslinked phenolic condensate, a non-crosslinked resorcinol-furfuraldehyde condensate, and a phenol-formaldehyde condensate; (ii) a rubber latex; (iii) a base; and (iv) an aldehyde component represented by structure (1), (2) or (3):

 wherein X is selected from the group consisting of oxygen, nitrogen and sulfur;

 wherein R 1 , R 2 and R 3 may be independently selected from the group consisting of alkyl, aryl, halo, hydrogen, and carboxylic functional groups;
wherein the water soluble condensate material contains sufficient resorcinol functional groups or phenol groups to allow for a reaction between the condensate material and the aldehyde component; and
(b) allowing the mixture to age at room temperature for at least about 8 to 24 hours.

2. The method of claim 1 , wherein the water soluble, phenolic condensate material is a resorcinol formaldehyde resin.

3. The method of claim 1 , wherein the aldehyde component is represented by structure (1).

4. The method of claim 3 , wherein the aldehyde component is 2-furfuraldehyde.

5. The method of claim 1 , wherein the latex component is selected from the group consisting of epoxy resin, functional rubber latex, unvulcanized rubber latex, and mixtures thereof.

6. The method of claim 5 , wherein the latex component is unvulcanized rubber latex.

7. A method for synthesizing a resorcinolic resin comprising the steps of:
(a) mixing 2-furfuraldehyde with a water soluble, phenolic condensate material selected from the group consisting of a non-crosslinked phenolic condensate, a non-crosslinked resorcinol-furfuraldehyde condensate, and a phenol-formaldehyde condensate;
(b) adding a base catalyst to the mixture of step a); and
(c) allowing the mixture to age at room temperature for at least about 8 to 24 hours.

8. A method for synthesizing a resorcinolic resin comprising the steps of:
(a) mixing 2-furfuraldehyde with a water soluble, non-crosslinked resorcinol-formaldehyde condensate material;
(b) adding a base catalyst to the mixture of step a); and
(c) allowing the mixture to age at room temperature for at least about 8 to 24 hours.
